Patented Oct. 6, 1908 orted by the uprights 14:. The solution 0 amber 12extends up'within the tank 3 to a greater height than the reactionchamber and said solution chamber is pro vided with the inverted conicalbottom 15. provided with the opening 16 to which the pipe 17 isconnected. This pipe 17 leads to the lime tank 18 to which it isconnected as at 19. This pipe 17 maybe provided with The lime tank 18 islocated upon the floor or foundation'21 Within the ho use 2-and saidtank is connected up to the slaking box 2 2 by means of the pipe 23; A.valve 23 con -.trols the communication between the slak-K .lng box '22and the lime tank 18. The

slaking box 22 is provided with the inclined bottom 24 and contains thelime which is to be slakedf and which then passes bythe ipe 23 into helime tank 18. The lime tan 18 is closed and is therefore under pressure.

1 The reaction tank 13 is provided with the internal batfles 25 and atits lower end is con nected up by the pipe 26 to the outlet or'exhaustof the motor 27. This motor 27 'may be ofan suitable construction, thatknovm as the Gould motor being particularly adapted for this purpose. Apipe 28 leading from the raw water supply is connected up with the motor27 and by means-of which the. said motor is operated. In this mannerthewater is admitted'under pressure and the exhaust thereof is carried upunder pressure into the reaction chamber to the u per end of the tank3'without other aid. T e motor 27 has the pitrnan 29 adjustably securedwithin guides 30, the opposite end of said pitman being connected up tothe ump 31, said ump being connected u to t e pipe 32 at its inlet andits exhaust eing connected up to the pi e 33 leading to the bottom ofthe lime tan ,18. In this manner the treated water 'onl passes throughthe pump 31 and is forcedt ereby through the tank 18 so as to drive'thelime Water therein through the pipe 17 into the saturater 12. Bythis con-- struction the lime waterdoes not pass through prevent itsproper operation and entail thenecessity of cleaning out the pumpfrequently different conditions. I

Within the lime tank '18 is a suitable mixer 34 for stirring up thecontents of said tank, and this mixer is driven by the belt 35 connectedup to the shaft of the motor 27. The

belt 35 drives the s rocket 36 on the shaft 37 which carries the evelpinion 38 -meshing. with the bevel pinion 39 upon the shaft car-' Irying the stirrer 34.

Located opposite the lime tank 18 is the soda tank 40 which has asuitable stirrer 41 therein driven by the belt 42in the same manner asthe stirrer in the lime tank 18. 'A suitable pump 43 is also provideddriven by the motor 27 in the same manner as the pump 31, said pump 43being ada ted to deiver the soda solution through t e pipe 44 into thereaction chamber 13 as at 45.

Within the chamber 12 the pipe 46 which is provided atits upper end withthe funnel 47. The ipe, 46 passes through the bottom 15 of the e amber12 and enters the reaction chamber 13 at 48. By admitting the lime waterto the reaction chamber at this point the water rises within thereaction chamber, meeting the flow of thehard water to be treatedentering the pipe 26 and-is carried up through said reaction chamberwithout theliability of the hard water, which enters-under pressure,forcing the lime water back through the pipe 46 into the chamber 12.

At the upper end of the tank 3 is the overflow trough 49 which collectsthe treated water and the pipe 32 connects with thisover-- 'flow trou hso that the treated water is. fed through t e'pump 31 and thence intothe lime tank 18. .A pipe 50 leads from the overflow trough to ca thetreated water down to the pi es 51 w 'ch are'controlledby valves 52 anwhich carry the treated water to the filters 53 and 54. Within the house22 are the bins 55 and 56 for the storage of lime and soda,respectively.

When our improved apparatus is in o eration the hard water to be treatedis con ucted from the supply and introduced by means of the pipe 28 tothe motor 27 and by its pressure acts to drive said motor, andconsequently the pumps 31 and 43. The water in assing through theexhaust of the motor 27' 1S earned by the pipe 26 up into thereactionchamber 13. Meanwhile, the pump 31 supplied with the treated water fromthe pipe 32 delivers this water to the lime tank 18 and the water isforced up through said tank and out through the pipe 17 into thesolution chamber 12. This is due to the fact that the -lime tank 18 isclosed and under pressure,

The lime is supplied by means of the pipe 23 from the slakmg box 22 tothe lime tank 18 in suitable quantities; while the stirrer 34 ters 53and 54, whlle a keeps the solution in thetank 18 properly mixed. When itis desired to admit the lime from the slaking box 22 to the lime tank18,the pump is stopped and the valve 20 in the pipe-17 is close By thisarrangement the ack flow into the slaking chamber 22 is avoided. Whenthe pqoper sup ly has been admitted from the sla g box t he valve 23 isclosed and thevalve 20 opened, whereupon the water is-forc'ed up throughthe lime tank and carries the lime through the .pipe 17. As the limewater passes through thepipe 1-7 upinto the saturater 12 itascends saidsaturater and overflows into the nozzle 47 whence it descends by thepipe 46 to the bottom of the reaction chamber 13. Here the lime meetsthe hard water and both are carried up through the baffles 25, becomingthoroughly min led as they rise. The lime water and her waterintermingled-in this manner overflow from the upper end of the reactionchamber 13 into the compartment 10 and flow down saidcompartment.

in the bottom of the tank 3 and the water ascends in the compartment 11gradually un tiliitoverflows into the trough 49 at the upper end of thetank 3. The treated water is then carried down by the pipe 50 to thefild E b h portiop tlfigreof is rawn o t e e32 to sup y t pum 31 withthe water f r the lime iiimk 18. WE omitted to mention that .thesodasolution is pumped from the tank 40 and introduced by means of the pipe44 to the reaction chamber at a pro er point so as to becomeintermingled with the lime and hard water in the reaction chamber.beforethe same fiowsinto the depositing com artment 10. g Y
